In a move that will undoubtedly frustrate Arsene Wenger, who has spoken previously of his concern over Sanchez’s staggering schedule over the last few years, the former Barcelona man could play up to eight times before he is back in an Arsenal shirt.

Chile will head to Russia for the Confederations Cup which begins on June 17, though they have three friendly matches against Burkina Faso, Russia and Romania scheduled before that.

If Chile qualify from their group, Sanchez can be expected to play two further games, with the Confederations Cup also including a third-place play-off.

Sanchez took part in the World Cup in 2014 before carrying his side’s hopes in back-to-back Copa Americas in 2015 and 2016.

Chile have picked an incredibly strong line-up for the tournament, with Manchester City’s Claudio Bravo and Juventus’ midfield dynamo Arturo Vidal also on the plane.

Sanchez has been heavily linked with a summer move away from Arsenal if the club fail to secure Champions League football on Sunday – they must beat Everton and hope Liverpool slip up at Middlesbrough.

Chelsea are thought to be making a big play for his signature, with Sanchez keen to remain in London if he does move clubs, while Paris Saint-Germain and Manchester United are also monitoring his situation with interest.
